In recent years, supercritical fluid chromatography (SFC) has become a powerful tool in modern analytical chemistry, and the diversity of stationary phases in SFC promotes phenyl-type phases to confront with a significant resurgence of interest. In this paper, a series of phenyl-type stationary phases with different substituted benzenes involving N-propylbenzamide (PB), 4-fluoro-N-propylbenzamide (PB-F), and 4-ethyl-N-propylbenzamide (PB-ET) were synthesized. Retention mechanism of these phases in SFC was investigated using a linear solvation energy relationship (LSER) model. The phenyl-type stationary phases with all positive parameters can provide all types of interaction, typically involving hydrogen bonding, dipole-dipole and dispersive interactions. The different benzene’s substituents of the stationary phases mainly affected their hydrogen bonding and dipole-dipole interactions, which could be reflected by the angle between the solvation vectors to some extent. The k-k plot showed that the selectivity difference of phenyl-type stationary phases was closely related to the type of solute. Thus, based on twenty-five natural phenolic compounds, two systems with high orthogonality (63.49%) were constructed using three columns, namely phenyl column (PHE) x PB-F and PB x PB-F. Finally, after investigating the influence of chromatographic conditions, ten flavonoids could be separated by using PB, PB-F and PHE columns in SFC. (C) 2019 Published by Elsevier B.V.

Cancer is one of the leading causes of death worldwide and requires intense and growing research investments from the public and private sectors. This is expected to lead to the development of new medicines. A determining factor in this process is the structural understanding of molecules with potential anticancer properties. Since the major compounds used in cancer therapies fail to encompass every spectrum of this disease, there is a clear need to research new molecules for this purpose. As it follows, we have studied the class of quinolinones that seem effective for such therapy. This paper describes the structural elucidation of a novel dihydroquinoline by single-crystal X-ray diffraction and spectroscopy characterization. Topology studies were carried through Hirshfeld surfaces analysis and molecular electrostatic potential map; electronic stability was evaluated from the calculated energy of frontier molecular orbitals. Additionally, in silico studies by molecular docking indicated that this dihydroquinoline could act as an anticancer agent due to their higher binding affinity with human aldehyde dehydrogenase 1A1 (ALDH 1A1). Tests in vitro were performed for VERO (normal human skin keratinocytes), B16F10 (mouse melanoma), and MDA-MB-231 (metastatic breast adenocarcinoma), and the results certified that compound as a potential anticancer agent.

Solid-contact ion-selective electrodes (SC-ISEs) have shown great potential for routine and portable ion detection. The introduction of nanomaterials as ion-to-electron transducers and the adoption of different performance-enhancement strategies have significantly promoted the development of SC-ISEs. Herein, new solid-contact ion-selective electrodes, along with the implementation of multiwalled carbon nanotubes (MWCNTs) as ion-to-electron transducers and potassium tetrakis (p-chlorophenyl) borate (KTpClB) as lipophilic ionic additives, were presented for the detection of isoproturon (IPU) and diuron (DU) herbicides. Molecularly imprinted polymers (MIPs), with special molecule recognition properties for isoproturon (IPU) and diuron (DU), were prepared, characterized, and introduced as sensory recognition materials in the presented electrodes. Sensors revealed a near-Nernstian response for both isoproturon (IPU) and diuron (DU) with slopes of 53.1 +/- 1.2 (r(2) = 0.997) and 57.2 +/- 0.3 (r(2) = 0.998) over the linear ranges of 2.2 x 10(-6)-1.0 x 10(-3) M and 3.2 x 10(-6)-1.0 x 10(-3) M with detection limits of 8.3 x 10(-7) and 1.4 x 10(-6) M, respectively. The response time of the presented sensors was found to be <5 s and the lifetime was at least eight weeks. The sensors exhibited good selectivity towards isoproturon (IPU) and diuron (DU) in comparison with some other herbicides, alkali, alkaline earth, and heavy metal ions. The presented sensors were successfully applied for the direct determination of isoproturon (IPU) and diuron (DU) in real water samples. HPLC of Formula: C7H8N2O.

Voltammetric sensor using a symmetrical derivative of anthrone3 (1,7-diamino-3,9-dibutyl benzo[1,2,3-de:4,5,6-d’e’]diquinoline-2,8(3H,9H)-dione) (SPE-A) has been developed as a probe for Hg(II) ions. Performance of the probe as screen-printed electrode modified with the receptor (SPE-A) has been compared with anthrone3 in solution phase, using 1:1 water-acetonitrile solvent system. Anthrone3 displayed an electrochemically quasi-reversible nature in voltammograms with both the systems and is presented as a novel disposable voltammetric sensor for mercury ions. Upon interaction with cations, both the electrode systems showed sensitivity towards Hg2+ ions with a lower detection limit of 0.61 mu M. The magnitude of the voltammetric current with the SPE-A exhibited three times the current obtained with a bare glassy carbon electrode (GC). Kinetic performance of the SPE-A electrode is better than the GC electrode. The morphological studies indicate reusability of the electrodes.

Four categories of sulfonic acid functionalized fiber catalysts with different surface microenvironments were synthesized by covalent grafting using polyacrylonitrile fiber (PANF) as the support. After the effect of acid structure on catalytic activity has been investigated by Friedlander reaction, PAN(EOS)F was chosen for the synthesis of quinolines and coumarin derivatives with high yields and extensive substrate scope (51 examples) in ethanol or water. The effect of electrostatic microenvironment and solvent has been discussed, and a release-catch-release-catch catalytic pattern was proposed accordingly. PAN(EOS)F can be easily recycled for 20 times without any decrease of catalytic activity. (C) 2019 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Any catalyst should be efficient and stable to be implemented in practice. This requirement is particularly valid for manganese hydrogenation catalysts. While representing a more sustainable alternative to conventional noble metal-based systems, manganese hydrogenation catalysts are prone to degrade under catalytic conditions once operation temperatures are high. Herein, we report a highly efficient Mn(I)-CNP pre-catalyst which gives rise to the excellent productivity (TOF degrees up to 41 000h(-1)) and stability (TON up to 200 000) in hydrogenation catalysis. This system enables near-quantitative hydrogenation of ketones, imines, aldehydes and formate esters at the catalyst loadings as low as 5-200 p.p.m. Our analysis points to the crucial role of the catalyst activation step for the catalytic performance and stability of the system. While conventional activation employing alkoxide bases can ultimately provide catalytically competent species under hydrogen atmosphere, activation of Mn(I) pre-catalyst with hydride donor promoters, e.g. KHBEt3, dramatically improves catalytic performance of the system and eliminates induction times associated with slow catalyst activation. Manganese-based hydrogenation catalysts are sensitive to high temperatures and may degrade under industrially relevant conditions. Here, the authors report a highly efficient manganese pincer pre-catalyst displaying high TOF values (up to 41 000 h(-1)) and stability (TON up to 200 000) at loadings as low as 5-200 ppm.

A series of 2-amino-4H-chromenes by combining dimedone, different substituted aromatic aldehydes and malononitrile and 5-substituted-1H-tetrazoles by combining variable aldehydes, hydroxylamine hydrochloride and sodium azide have been efficiently synthesized in presence of ethylenediamine functionalized cellulose acetate as a solid base catalyst i.e Cellulose acetate[1,2-ethylenediamine][CAEDA]. This catalyst is low-cost, non-toxic, unexplored, easily available, reusable, eco-friendly in nature. This synthesized solid base catalyst has been characterized by fourier transform infrared spectroscopy (FTIR), themogravimetric analysis (TGA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) spectroscopic techniques. The new catalytic method exhibits some noteworthy advantages such as short reaction time, high yields, easy workup and purification steps, simple preparation method which makes this strategy more useful for the synthesis of chromene and tetrazole derivatives then earlier methods.

The design of functionalized porous materials is an important research direction in material science, especially for fluorine-containing materials with enhanced thermal/oxidative stability, lower dielectric constants, and better gas-selective permeation. In this work, a series of poly(phenyl-alkane)s of intrinsic microporosity (PIM-xR) were synthesized by the methanesulfonic acid-catalyzed Friedel-Crafts hydroxyalkylation polycondensation of contorted and rigid multibenzene and benzaldehyde derivatives. The PIM-xR exhibited good thermal stability, excellent solution processability, and high Brunauer-Emmett-Teller (BET) surface areas (400-1200 m(2) g(-1)). The physicochemical properties and applications of PIM-xR could be tuned by the type, quantity, distribution, and postmodification of substituents on the benzaldehyde derivatives. Unlike other contorted and rigid multibenzene derivatives, only electron-rich spirobiindane derivatives directly produced soluble, linear, high-molecular-weight polymers without cross-linking because spirobiindane possesses three t-butyl-like structural units that provide large steric hindrance at potential reactive sites. Subsequently, a series of fluorinated PIMs (PIM-xF) with different fluorine contents and distributions were explored, and the relationship between the microporosity of PIM-xR and degrees of rotational freedom of the polymer chains was analyzed using these PIM-xF. Flexible and transparent PIM-xF membranes were easily obtained by solution processing and exhibited high gas permeabilities and moderate permeability selectivity. In particular, the CO2/N-2 separation performance of the PIM-5F membrane exceeded the 2008 Robeson’s upper bound (P-CO2 = 3240 barrer and alpha((CO2/N2)) = 27.9). This work provides a facile method for the precise design and preparation of fluorinated or other functionalized porous materials for environmental and energy applications.

According to Article 12 of Regulation (EC) No396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance fluometuron. To assess the occurrence of fluometuron residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Commission Regulation (EC) No33/2008 as well as the European authorisations reported by Member States (including the supporting residues data). Based on the assessment of the available data, an MRL proposal was derived and a consumer risk assessment was carried out. All information required by the regulatory framework was present and a risk to consumers was not identified. In addition, EFSA identified some data gaps which are not expected to impact on the validity of the MRL derived but which might have an impact on national authorisations.
